Yesterday, after my car was in the sun all day, I started the car and the M button did not work. It did not light up and did not produce the right settings. I restarted the car numerous times to no avail. The power and EDC buttons worked fine however. I was at a party and two hours later, in the early evening, I restarted the car and it worked fine. Has anybody had that problem? Does it have to do with ambient temperature and overheated engine compartment?
